EMBROlDERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 562,675, dated June 23, 1896.

Application filed March 6, 1894. Serial No. 502,571. (No model.) Patented in England May 16, 1893, No. 9,759; in France May 17,1893,No.230,147,' in Belgium May 27, 1893,110. 104,844, and in Italy May 30,1893, no. 34,151,

To aZZ whom it may concern.-

Be it known that I, HEINRICH SPllI-IL, a citizen of the Confederation of Switzerland, and a resident of St. Gall, in the Republic of Switzerland, have invented a new and useful Device for Running the Carriages of Embroidering-Wlachines To and Fro, (for which patents have been obtained in'Italy, No. 3%,151, dated May 30, 1893, in Great Britain, No. 9,759, dated May 16, 1893; in France, No. 230,147, dated May 17, 1893, and in Belgium, No. 104., 844, dated May 27, 1893,) of which the following is a specification.

This invention refers to that class of embroidery-machines which are known as Heilmann embroidery machines, and my improvements in machines of this sort relate to certain arrangements and combinations of parts, for the purpose of running the carriage to and fro in a more regular and reliable manner, and also for coupling the carriages with, and uncoupling them from, the driving-shaft, so as to set them at rest, or drive them by hand, as will be more fully described hereinafter.

In order to make my invention more clear, I refer to the accompanying drawings, in which similar letters denote similar parts throughout the several views, and in which- Figure 1 shows a portion of the lower part of a Heilmann embroidery-machine, the parts unnecessary for moving the carriages being left away. Fig. 2 is a vertical section through the driving and coupling mechanism, drawn on a larger scale. Fig. 3 shows some details of the driving mechanism in front view, also in the larger scale of Fig. 2. Fig. 4. shows the upper portion of the right-hand part of Fig. 1, drawn on a larger scale, some mechanisms being added to show the connection between the needle-carriage and the driving-belt; and Fig. 5 is a rear View of the parts shown in Fig. 4, the right-hand pin-roller of Fig. 4 being left away.

The spur-wheel 1, Fig. 2, which is situated on, an d firmly connected with,the rearwardlyprotruding nave of the bevel-wheel 2, is driven from the vertical shaft 3 by means of bevelwheel at. XVheel 1 contains a cam-groove 5, into which take the bowls 6 and 7, Fig. 3, at

tached to the oscillating levers 8 and 9, having their fulcrums at 10 and 11. Vhile these oscillating levers are in their outer positions, corresponding with the inward travel of the carriages, and the bowls (3 and 7 are in the concentric part of the groove 5, the same are drawn by the eccentric part of the latter toward the center of wheel 1, and cause by means of the links 12 and 13 and the arms 11 and 15 a partial rotation of the pin-rollers 16 and 17, the straps 18 and 19 of which take with them the carriages 20 and 21, Fig. 1, in the well-known manner.

For the sake of distinctness I have shown in Figs. 4 and 5 the connection between the carriages and their driving-belts. This con nection is established by means of angular pieces 30, the vertical legs of which are secured to the lower part of the frame of the carriage, whereas the horizontal leg of each of said angular pieces is connected with the respective belt.

The cam-groove 5 is formed in such a manner that the outward travel of each carriage is only about seventy-five millimeters. This movement may be performed also by hand, if necessary for the mounting of the fabric. For this purpose double clutches 22, Fig. 2, are arranged on the shafts 23 and 24:, Fig. 3, of the pin-rollers 16 and 17 in such a manner that the same are compelled to rotate with the shafts 23 and 24, but maybe displaced longitudinally on them. Each of these shafts has loosely attached to it a crank-handle 25, Fig. 2, the boss 26 of which forms one of the two counterparts for the double clutch 22. The other counterpart 27 of each double clutch is secured to the arms 1% and 15. The clutches may be displaced by levers 28, Fig. 1, fulcrumed at 29 to the frame of the machine, and taking into the circular grooves of the said clutches. Thus, if the double clutch 22 is coupled with the lever 9, Fig. 2, by means of link 13 and arm 15, an automatic play of the carriages (outward and inward) takes place, but if coupled with the boss of the crank-handle the respective carriage can be run in and out by means of the same. If the double clutch is neither coupled with arm 15 nor with the boss 26, the respective carriage 21 can be completely drawn out on its rails, so as to give free access to the frame on which the fabric is mounted.

Having thus fully described the nature of this invention,what I desire to secure by Letters Patent of the United States is- 1. In an embroidery-machine, the combina tion with the carriages of the same, pin-rollers arranged on shafts, and belts connecting said carriages with said pin-rollers, of a drivingwheel 1 having a cam-groove 5; oscillating levers 8 9 having bowls 6 7 taking into said cam-groove; crank-arms 14, attached to said shafts; and links 12, 13 connecting said crank-arms with said oscillating levers, substantially as described.

2., In an embroidery-machine, the combination with the carriages of the same, pin-rollers arranged on shafts, beltsconnecting said carriages with said pin-rollers, means adapted to turn said shafts,,and crank-arms connecting the shaftsto said means, of crank-handles secured also to the said shafts; double clutches 22 arranged upon the latter between the bosses of said crank-arms and said crankhandles, and adapted to be rotated with, and 3 to be longitudinallydisplaced upon, the shafts; clutch counterparts 26, 27' secured to said bosses; and levers 28 adapted to displace said double clutches, substantially as described.

3. In an embroidery-machine, the combination with the carriages of the same, pin-rollers arranged on shafts and belts connecting said carriages with said pin-rollers, of a drivingwheel 1 having a cam-groove 5 oscillating levers 8 9 having bowls 6 7 taking into said :cam-groove; crank-arms 14, 15 attached to said shafts; links 12, 13 connecting said crank-arms with said oscillating levers; crank-handles 25 secured also to the said shafts double clutches 22 arranged upon the latter between the bosses of said crank-arms .and said crank-handles, and adapted to be rotated with, and to be longitudinally displaced upon, the shafts; clutch counterparts 26, 27 secured to said bosses; and levers 28 adapted to displace said double clutches, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
